SAFE Perimeter UAS & Facilities Defense

Counter-UAS and Wireless Airspace Defense for Installations and Federal Facilities

Passive detection of the aerial and RF threats a perimeter cannot stop — deployed at U.S. military installations, in joint interagency environments, and across critical infrastructure with a federal nexus.

Where We Deploy

One sensing architecture, adapted to the operating picture each command already runs.

Installation Defense

Persistent airspace and spectrum coverage over flight lines, ranges, housing, and restricted areas — with operator geolocation, not just contact reporting.

Force Protection

Detection during power-up and pre-flight, frequently before an aircraft leaves the ground and well outside the fence line.

Federal Facilities

Diplomatic premises, federal buildings, SCIFs and no-wireless zones — where policy assumes an air gap and nobody has measured it.

Joint & Interagency

Task force environments, exercise and evaluation support, and coalition operations where systems must plug into an existing common operating picture.

Layered Counter-UAS

No Single Sensor Sees Everything

Each detection modality is blind to a specific and well-understood class of aircraft. Layering is what keeps one countermeasure from collapsing the entire picture.

  • RF detects the control link and geolocates the operator — but not an aircraft flying a pre-loaded waypoint mission with its radio off.
  • Acoustic detects the one signature a flying object cannot suppress, at shorter range.
  • Radar sees physical returns, but small aircraft low against clutter sit at the edge of its envelope.
  • EO/IR confirms and identifies visually, but needs a cue and clear line of sight.
The threat that defeats RF

Fiber-optic tethered and pre-programmed autonomous aircraft are built specifically to beat RF and GPS-based counter-UAS. They cannot beat physics — anything that flies moves air, and moving air makes sound.

The Systems

Detection, Sensing, and Where Authority Applies

Deployed as a layered architecture or fielded individually against a specific requirement.

SkyShield dome counter-UAS detection unit

SkyShield — RF Drone Detection

7–14 km, 360°. Fixed, vehicle, or aircraft mounted, or deployed from a transport case in under an hour.
500+ signatures. AI-enabled classification across commercial, hobbyist, and DIY-built airframes.
Operator geolocation. RF direction finding locates the controller, not just the aircraft.
Passive. Emits nothing. Detection triggers on the control link during power-up and pre-flight.
Bands. 2.4, 5.2, 5.8 GHz and 915, 868, 433 MHz.
AirShield wireless intrusion detection sensor

AirShield — Wireless Intrusion Detection

300 MHz to 6 GHz. Software-defined radio across Wi-Fi, cellular 2G–5G and CBRS, Bluetooth and BLE, LPWAN, and GPS.
~25,000 sq ft per sensor. PoE mounted, with LTE backhaul where production network access is undesirable.
Validates the air gap. Proves whether a no-wireless zone is actually clean rather than assumed clean.
Next-generation TSCM. Continuous monitoring rather than a periodic sweep that is stale the day after it ends.
Forensic record. Time-synchronized RF logs, replayable after the fact.
Acoustic detection of non-emitting aircraft

SkyShield Sentry — Acoustic Detection

Detects what RF cannot. Fiber-optic tethered and pre-programmed autonomous aircraft with no control link to intercept.
2,000 m detection, 1,000 m engagement. Up to 98 interceptors per 10×10 grid.
Non-emitting. Acoustic sensing with AI classification and high clutter rejection.
GPS-denied capable. Full operation in RF-congested and GPS-denied environments.
Autonomous. No skilled operator required; network-ready for external C2.
Portable counter-UAS detection kit

SkyShield Mobile & LOCH Detector

Mobile: 3–7 km. Handheld and backpack-portable, MOLLE compatible, 4.5–6 hours on battery, ATAK compatible.
No installation. Operates from a vehicle, backpack, or tactical hardcase for forward and expeditionary use.
LOCH Detector. IMSI detection and location in man-portable, covert, vehicle, and UAV payload configurations.
MIL-STD-461F / 810G. IP67 rated, dual-channel minimum, Five Eyes compliant, swarm capable.
Restricted. Available to qualified government and law enforcement end users with applicable authority.
Detection and Mitigation

What Your Authority Actually Permits

The single most consequential question in scoping a counter-UAS program, and the one most often answered after the purchase order.

Detection carries no equivalent restriction to mitigation. That is why detection-first architecture is the practical starting point for nearly every program — and why it positions a command to act quickly if authority expands, because the sensing layer is already in place.

  • 10 U.S.C. § 130i — the Department of War (still the Department of Defense as a matter of statute) and the Department of Energy.
  • 6 U.S.C. § 124n — the Department of Homeland Security and the Department of Justice.
  • State and local agencies and private operators do not currently hold independent mitigation authority.
On terminology

SkyShield and AirShield perform electronic support and contribute to electronic protection. SkyWall is an electronic attack capability, fielded only to operators with the authority to employ one. We describe each capability by what it does, because that is what keeps a program moving through the right approval chain.

Statutory citations current as of publication. Authority provisions are amended periodically; confirm current status with your judge advocate or counsel.

Fielded where authority exists
SkyWall RF mitigation360° protection to a 2–3 km radius, with automated, manual wideband, and smart selective modes when integrated with SkyShield detection and direction finding. Procurement requires a completed end-user certificate.
Sentry kinetic interceptNon-RF interception for aircraft that RF-based mitigation structurally cannot reach.
Wireless-layer enforcementA separate matter from aerial mitigation, and available far more broadly — network security action against identified threats inside an environment you control.
Integration

Into the Picture You Already Run

A sensor that needs its own dedicated screen adds a task. A sensor that pushes contacts into the common operating picture adds capability without adding manning.

  • ATAK. SkyShield Mobile pushes live contacts directly into ATAK.
  • Digital battle management. Simple APIs for integration with existing C2 systems.
  • Tactical MANET radios. Compatible with fielded mesh networking.
  • SIEM and SOAR. Wireless events flow into the workflow analysts already use.
  • Rapid deployment. Dome configuration operational in field conditions in well under an hour.
Operational history

SkyShield and AirShield have been deployed and evaluated at U.S. military installations, in Department of War test and evaluation activity, in joint interagency task force environments, and across critical infrastructure — under live operational conditions rather than in a laboratory. Current deployments include continuous 24-hour counter-UAS monitoring and reporting at active installations.

Acquisition paths

The SkyShield product line is available on GSA Schedule through our distribution partners, with first-year hardware and software support warranty included on core systems. Department of War, federal civilian, and state and local buyers can all acquire through this path. For programs with grant funding, the FEMA Counter-UAS Grant Program provides a separate route — see the FAQ for eligible uses.
